Description

Building steel mould inside shuttering support device

The utility model relates to a kind of steel form for buildings inner formword and supports device, particularly a kind of device that supports that utilizes simple and easy oil pressure unit (as jack etc.) to support to set up template within the building iron template of finishing.

The inventor once invented a kind of construction formwork, can set up template in the building site very easily, and after concrete grouting finished, its operation of moving back mould was also very easy; Because technology really belongs to innovation, thus obtaining United States Patent (USP) the 4th, 679 respectively, No. 762, and the 4th, 667, No. 923 technology contents is narrated explanation; See also shown in Figure 1, Figure 11 of itself that is above-mentioned United States Patent (USP), we can understand, the template in this building operations, it mainly is to set up inner formword 10 earlier, and then the exterior sheathing 12 of slinging, and makes exterior sheathing 12 borrow the fixing of inner formword 10 and carried; In addition, between inner formword 10 and the exterior sheathing 12 nearly lower ends, in order to interlink, and keep distance between the desire grouting, normally be provided with most spacers (Spacer) 13 between the two, the shape of spacer can resemble shown in the spacer 13 among the figure, shape that also can be shown in spacer 14, no matter but the spacer of which kind of form, it installs essential will boring in template 10 and 12, and is locked.After template erection finishes, comprise the metope 15 that is defined with inner and outer template 10,12, and the floor 17 that defined of template 16, the grouting operation of the concrete that carries out again, but so concrete metope of once-forming and floor.

In above-mentioned building construction process, it is easy to bring into play template erection really, shortens the time of the shut die and the demoulding, makes the advantage that the building time can shorten dramatically.But, the inventor, finds to still have some can improve part at this class template of practice in process of the test, is presented below now:

(1), because construction formwork is as panel with steel plate, and its back is provided with the skeleton support, concrete lateral pressure is very big when grouting, particularly at the nearly base portion place of inner and outer template, tend to cause curving inwardly of inner formword 10 integral panels, and the metope after the moulding that makes becomes not straight, and arc slightly.The inventor finds the maximum displacement that inner formword 10 bends inwards even can reach 5 centimeters, so necessity of being improved certainly will be arranged in actual tests.

(2), as shown in Figure 1, side system relies on the metope 18 of lower floor, so in a single day in the concrete grouting process, when inside and outside template struts because of the lateral pressure that is subjected to concrete under the exterior sheathing 12, because there is spacer 13 to connect between inner and outer template 10 and 12, so no matter the generation template is inside or when outer displacement, all will affect the metope 18 of lower floor, if the structure of this lower floor's metope 20 is firm inadequately, certainly will be destroyed, or damaged the complete of its structure.

(3), the height of common first floor is about three meters, so template is highly quite high; And between the inner and outer template 10,12 in order to guarantee certain interval, and prevent that the lateral pressure because of grouted-aggregate concrete from making among inner and outer template 10 and 12, following spacer segment is changed, so established

many spacers

13,14 etc.; The installation of these spacers must be holed on the panel of construction formwork, and the lock(ing) bolt etc. of spacer is locked on the skeleton of punching block, so the engineering that punching block sets up in the building site is still comparatively complicated; Simultaneously, because the essential boring of the panel of punching block also just influences the feasibility that punching block heavily covers use, and greatly reduces the utilization benefit of punching block.

In sum, the main purpose of the utility model promptly is to provide a kind of bracing or strutting arrangement of steel form for buildings inner formword, can guarantee that the template of setting up is unlikely to bend in construction, and can set simultaneously between the inner and outer template every, and do not need will be on the steel panel boring and install spacer additional.

Another purpose of the utility model is providing a kind of device that supports of punching block inner formword, and the lower floor's metope and the floor that cooperate one to finish make the lateral pressure of concrete in the time of not only can bearing grouting between inner and outer template, and will not affect and influence the structure of lower floor.

It is one to have the block that supports of four-limbed that punching block inner formword of the present utility model supports the preferred embodiment of one of device, when floor grouting operation is finished, can be installed in the position that floor preestablishes with supporting block, and pin is stretched in the concrete; Again, the side that supports block is provided with for supporting the bead that block pulls up, and which is provided with screw, can utilize a screw to pass and towards the floor application of force, can will support block jack-up, supports the operation that piece pulls up and finish.

The principal character that the punching block inner formword of the utility model supports device is that being provided with most in abutting connection with peripheral region on the floor of floor of institute's desire building supports Chinese toons, and to support device, as jack etc., support in supporting between Chinese toon and the inner formword, and obtain supporting to arrive in of desirable inner formword.

For reaching above-mentioned purpose, the utility model steel form for buildings inner formword supports technological means and some preferred embodiments that device adopts, now cooperate diagram to be described in detail as follows, in the hope of making your juror other advantage to the utility model, purpose and feature obtain to understand more clearly.

Secondly, see also Fig. 3 and cooperate and consult shown in Figure 4ly, construction formwork comprises an exterior sheathing 40 and an inner formword 41, and its apical margin forms a

flange

42 and 43 respectively; Be respectively equipped with the Connection Block 51 and 52 of linkage 50 on the inner and outer template on the

flange

42 and 43, more be provided with pair of

locking bolt

53 and 54 on each Connection Block 51 and 52,

locking bolt

53 and 54 is a square frame shape, the size of square opening is suitable with the cross section of a pitman 55 substantially, and can pass therein for pitman 55,

locking bolt

53 and 54 end faces more are provided with a screw 46,57, set a bolt 56,59 in it.We can very simple understanding, utilize pitman 55 to be arranged in the

locking bolt

53 and 54, and regulate between two inner and

outer templates

41 and 40 every after,

bolt

58 and 59 is locked screw 56 and 57,

bolt

58 and 59 end will be packed on the pitman 55, end obtains desired binding on inner and

outer template

41 and 40 and make, and keeps certain interval; In addition, because linkage 50 can equipment above inner and

outer template

41 and 40 have most groups, thus can very make inside and outside 41 and 40 top most groups be arranged equipment securely, so can make inner and outer template acquisition combination securely by ten minutes.

Still see also Fig. 3, also outside projection one flange 44 of side under the exterior sheathing, it utilizes one group of fastening devices 60 that edge is combined with metope 21 and fixes.Fastening devices 60 can be provided with most groups on flange 44, comprise a linking arm 61, and the one end borrows bolt 62 to be fixed on the flange 44, and the other end then is provided with a perforation 63; One bolt block 64 has female threaded hole in it, can imbed in the metope 21; And a bolt 65, pass perforation 63, and be screwed in the female threaded hole of bolt block 64, the side is combined with metope 21 fix.

Still see also shown in Figure 3ly, inner formword 41 belows are provided with a flange 45, and flange 45 is to put in one of floor 22 upper flanges 45 end to be provided with an end face 46, this end face 46 be located on the floor 22 the support plane that supports Chinese toon 30 31 in correspondence with each other; At end face 46 and support and to set up one between the support plane 31 of Chinese toon 30 and support equipment 70, usually can be a easiest hydraulic cylinder or a hydraulic jack, or the general mechanical type jack that cooperates start with screw rod, the piston rod 71 that utilizes the base of hydraulic cylinder or hydraulic jack and can rise props up aforementioned flange end face 46 respectively and supports Chinese toon support plane 31, and the length that piston 71 is stretched out just in time can keep certain interval with exterior sheathing 40 by control inner formword 41.

By template erection situation shown in Figure 3, and the arrangement that inner formword supports device as can be known, because the exterior sheathing of the metope that exterior sheathing 40 common and adjacent institute's desires are in the milk is combined with each other, so exterior sheathing 40 can be resisted sizable concrete lateral pressure.Again, edge under the inner formword 41 because and inner formword support the equipment that supports 70 in the device and support Chinese toon 30 and support mutually, so inner formword 41 also can bear very big concrete lateral pressure, and can not bend or the situation of displacement.

Consult Fig. 5, support the stereogram that supports block in another preferred embodiment of device for the utility model construction formwork inner formword, support block 80 and be a block substantially, rectangle slightly, and from the support plane 81 in its place ahead and backward general plan is skewed, the bottom surface of its body 82 is rearward stretched out the pin 83 of four symmetries downwards, then be provided with in side nearby and rear position respectively on the two sides 84 of body 82 two slightly with the

bead

85 and 86 of horizontal plane inclination, be equipped with a screw that runs through 87 and 88 on each

bead

85 and 86.

Aforementioned when supporting block 80 when using, mainly be supporting Chinese toon 30 and after use, must be beaten and remove in avoiding Fig. 2 as described above, and support the use of Chinese toon 30, always might be because the structure of grouting when one-body molded when not fine and close, and cause ruined situation when stressed.It is quite different that use supports block 80, it can be in the milk operation when finishing at floor, put one by one and be installed on the floor, the application of force slightly, and make the four-limbed 83 that supports block 80, go deep among the concrete, and make support plane 81 towards the inner formword desiring to support, in case after the concrete setting, promptly fixedly finish; We are realized that, this supports block 80 when when supporting inner formword, and its is can application of force quite big, general because its four pin 83 is to go deep in the concrete, and is rearward to stretch out, so but the application of force sizable degree extremely.

After template grouting operation is finished, desire will support that block 80 is chosen and for heavily covering use, see also shown in Figure 6, generally speaking, if the instrument with crow bar and so on can lever up supporting block 80, but because its pin 83 is oblique going deep in the concrete, so concrete for fear of the infringement floor, the utility model more provides one to be located at four beads 85 that have that support on block 80 two

sides

84,86 etc., screw 87 on it, the direction of the direction of 88 grades and pin 83 is roughly suitable, if screw in screw 87 with screw 89, among 88 grades, and facing to the floor application of force, can make supporting block 80 and on floor, levering up.And, because one of screw 89 end is sharp usually, if during facing to the concrete floor application of force, may pierce in the concrete, or on flooring, skid, support block 80 and separate and cause to make with concrete, so support block 80 can be under

near bead

85,86 etc. with equipment one backing plate 90, its one side is provided with lobe 91, and can be for firmly grasping with the concrete floor face, another side then supplies supporting of screw 89, and by the effect of screw 89 with screw 87, and can extract in the middle of floorslab concrete supporting block 80 smoothly; The part of only representing bead 85 among Fig. 6, and during practical operation to support block 80 and can steadily extract in order to make, and does not damage floorslab concrete, can there is no harm in simultaneously four groups of bead positions and all be operated by means of screw.This supports piece can heavily cover use.

In sum, the construction formwork inner formword of the utility model supports device, and certain Nover practical, and can reach and make not bending displacement of inner formword needn't be holed on the template, and does not influence the effect of the structure etc. of substrustion, really is a very creation of practicality.
